PURPOSE To quantify the prevalence of radiographic hand osteoarthritis (OA) among a group of community-dwelling individuals. Joint-specific prevalence rates/100 of radiographic OA of the hand were quantified and reported by age, gender, and dominant hand. METHODS Data from a community-based, longitudinal study designed to follow the natural history of OA(More)
A retrospective review of weight-bearing roentgenograms of 2197 knees in 1894 patients with symptomatic idiopathic osteoarthritis (IOA) revealed six different patterns of tibiofemoral deformity. Five of these patterns expand the taxonomic concepts of Ahlback; the sixth, "nonproliferative," was previously undescribed. It was seen exclusively in patients with(More)
OBJECTIVE To evaluate the association between weather (barometric pressure, precipitation and temperature) and pain among individuals with osteoarthritis (OA) (n=154) at the following sites: neck, hand, shoulder, knee and foot. METHODS This prospective study evaluated men and women, aged 49-90 yr, participating in a community-based, osteoarthritis(More)
Forty-eight patients who underwent 55 arthroscopic subcutaneous lateral retinacular releases with an average follow-up period of 15 months were examined. Advancing age, postoperative hemarthrosis, incomplete release, incomplete quadriceps rehabilitation, and severe ligamentous laxity are factors that may contribute to a poor result following this procedure.(More)
OBJECTIVE To evaluate the association between cigarette smoking and the subsequent development of osteoarthritis (OA) at four separate sites: knee, hand, foot and cervical spine. METHODS This cohort study examined 2505 men and women aged 40 years and older participating in the longitudinal Clearwater Osteoarthritis Study (1988-current). Biennial physical(More)
OBJECTIVE To evaluate the association between acute joint injury to the knee and knee osteoarthritis (OA). DESIGN Prospective cohort. Sample size = 1,436. Men and women aged 40 years and older participating in the population-based Clearwater Osteoarthritis Study (1988-current) with biennial physical exams including serial radiographs. Radiologically(More)
OBJECTIVE To quantify the association between radiographic foot osteoarthritis (OA) and radiographic OA at four joints: second distal interphalangeal (DIP), third proximal interphalangeal (PIP), first carpometacarpal (CMC), and the knee. METHODS Data collected for the Clearwater Osteoarthritis Study (COS) were analyzed (N=3436). The study outcome was(More)
BACKGROUND Rapid fistula healing may predispose Crohn's disease patients to abscess development. AIM Data from ACCENT II were analysed to determine whether fistula-related abscess development is affected by infliximab exposure. METHODS Following infliximab 5 mg/kg infusions at weeks 0, 2 and 6, patients were evaluated for fistula response for two(More)
OBJECTIVE To evaluate therapeutic success [defined as lack of total knee replacement surgery (TKR) or other significant clinical intervention during a 6-month follow-up] and to identify baseline patient and disease characteristics associated with improved pain relief and quality of life (QOL) in patients in a clinical practice who were treated with a single(More)
